Hi, Connected to host, simply remove the connection. Let’s assume the old and the new interface have the same device name, for example, eno2:
nmcli con del eno2 And then add the new interface to the bond: nmcli connection add type ethernet \ slave-type bond \ con-name eno2 \ ifname eno2 \ 802-3-ethernet.auto-negotiate yes \ master bond0 Change the con-name and ifname accordingly to your device name.

We have changed the network card of a hypervisor which uses bonding interface. The bonding interface still uses the old MAC address of the former slave interface. We tried to modify it via CLI but it didn't work, as soon as the node (hypervisor) is activated, the old MAC is reestablished. it seems to be backed up somewhere. Should we reinstall the host? Regards.
